Growing up in a musical family he was strongly influenced by his father Richard (former songwriter and drummer of the "Keymen") who wrote the #1 single, "A Kiss In The Dark" in 1966. With a desire to learn it all, Brion was playing drums and guitar by age 6 and soon building basement studios out of egg crates and 2track recorders. His first band soon followed, and by age 16 had already worked as a sound engineer for several bands and studios, found airtime on a local radio station for two self produced songs and received a teaching certificate in guitar from music icon, Dr. Linda Thompson (Julliard school of music).
Gamboa got his first taste of stardom when he became a founding member, lead singer and lead guitarist of the national rock group "Third Mist". Who later, for a television audience of over 40 million viewers, climbed to a semi-finalist position on the nationally syndicated show "Star Search" in the 90’s. Gamboa also produced a large charity concert (Unity Of Music Against Drugs) sponsored in part by MTV, and wrote the theme song "We Have The Voice" played in high schools throughout the United States.
Over the years Brion has continued to work as a Performer, Producer, Engineer and session player in many studios including his own “Sound Mission Studio”. He has performed for U.S. Troops with AFE (Armed Forces Entertainment) and has appeared with several national acts including “Myriad” and “On Tracy Lane”.
Gamboa has won numerous awards in Songwriting, Vocal Performance and Guitar as well as becoming a highly respected Producer/Engineer.
